A lot of evidence suggests that these nutrients may protect you against heart disease, prostate cancer and degeneration of the macula, the part of your eye that lets you see fine details like newsprint. In clinical studies, people who ate olestra had reduced carotenoid levels in their blood. However, since researchers still aren't quite sure how or even if carotenoids might prevent these diseases, it's hard to say whether olestra's effect on carotenoid levels is harmful to health.
Olestra also has one drawback common to many indigestible substances like dietary fiber or cellulose.
These substances simply pass straight through your system, so eating too much at once can cause you some problems. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close. Mobile Newsletter chat dots.

The vast majority of people can thoroughly enjoy snacks made with Olean cooking oil, and will not notice any effects. In fact, a recent study published in the Journal of the American Medical Association January 14, found that people eating Olean chips report no more digestive symptoms than those eating full-fat chips in a single sitting.
A nationwide survey conducted before Olean snacks were ever sold found that 41 percent of people reported one or more digestive symptoms within the month prior to the survey. This shows that digestive effects are very common, and can have many causes.

However, Olestra is synthesized using a sucrose molecule, which can support from six to eight fatty acid chains [3] arranged radially like an octopus, and is too large to move through the intestinal wall. Olestra has the same taste and mouthfeel as fat, but since it does not contain glycerol and the fatty acid tails can not be removed from the sucrose molecule for digestion, it passes through the digestive system without being absorbed and adds no calories or nutritive value to the diet.
From a mechanical point of view, scientists were able to manipulate the compound in such a way that it could be used in place of cooking oils in the preparation of many types of food Nestle, , Since it contains fatty acid functional groups , Olestra is able to dissolve lipid-soluble vitamins such as vitamin D , vitamin E, vitamin K , and vitamin A , along with carotenoids.
Fat soluble nutrients consumed along with Olestra products are excreted along with the undigested Olestra molecules. To counteract this loss of nutrient, products made with Olestra are fortified with oil soluble vitamins to compensate for this loss to fecal matter. But, outside of the popular culture disapproval of the product, many consumers simply did not see the speedy results for which they had hoped from a product they saw as being a cure all. This was due to the fact that Olestra only dealt with the fat component of the overall dietary pattern of Americans.
Foods containing olestra do contain calories and many Americans believed that they could just eat more of them to compensate for the less "saved" Nestle Eating olestra chips was not a particularly efficient way to improve one's diet overall.
In , researchers discovered that Olestra helps facilitate the removal of dioxins from the body, as it apparently binds to dioxins in a manner similar to that of normal fats. This unexpected side effect may make the substance useful in treating victims of dioxin poisoning. Read what you need to know about our industry portal chemeurope. My watch list my.
